The New York Post reported on Tuesday that Marbury is set to return for a third time after the death of his father earlier this month and play in Orlando against the Magic on Wednesday.
But later on Tuesday the New York Daily News cited a team official saying that Marbury did not travel with the team and likely wouldn't play.
Marbury has missed seven of his team's last 11 games following the death of his father on Dec. 2. The Knicks have gone 3-8 during that stretch.
Marbury took his third leave last Thursday after skipping practice because of a combination of flu-like symptoms and personal reasons. He was in uniform but did not play in New York's win over Cleveland the night before.
Earlier this season Marbury skipped a trip to Phoenix and was fined $195,000 by the team. He is appealing.
The Knicks, who are 8-19, have also been dealing with rumors regarding the job status of coach Isiah Thomas.
Multiple media outlets are reporting that Thomas may shake up the Knicks' lineup, benching either center Eddy Curry or forward Zach Randolph, who was acquired from Portland in the offseason. It's thought that the games of the two wide bodies are not complementary.
